What is Upstream Repository in GIT?

Upstream repository is the Parent/Original repository from where you forked your repository.

What is Fork?

A fork is a copy of a repository. Forking a repository allows you to freely experiment with changes without affecting the original project.

When a repository is cloned, it has a default remote called Origin that points to your fork on GitHub, not the original repository it was forked from.
To keep track of the original repository, you need to add another remote named

How to configure a Upstream repository?
  • Change Directory to your fork repository on your local computer and run below command(please change the upstream when you run command)
git remote add upstream https://github.com/abhishekamralkar/emacs.d

You can verify it by below command

git remote -v
Below should be the output
origin [email protected]:abhishekamralkar/emacs.d.git (fetch)
origin [email protected]:abhishekamralkar/emacs.d.git (push)
upstream https://github.com/aa/emacs.d (fetch)
upstream https://github.com/aa/emacs.d (push)

To sync the forked repository with the upstream repository follow below steps
